Researchers at the Lifelong Brain and Cognition Lab at the Beckman Institute for Advanced Science and Technology at the University of Illinois have utilized the magnetic resonance imaging (MRI) facilities available in Beckman's Biomedical Imaging Center to measure the moment - to - moment variability in brain activity, more specifically in the blood oxygenation level - dependent (BOLD) signal.
BOLD denotes blood - oxygenation - level — dependent.
